Traits
Illumination
The worm sheds dim light in a 20-foot radius.
Radiant Mirror
If the worm takes radiant damage, each creature within 20 feet of it takes that damage as well.
Tunneler
The worm can burrow through solid rock at half its burrowing speed and leaves a 10-foot-diameter tunnel in its wake.
Actions
Multiattack
The worm makes two attacks: one with its barbed tentacles and one with its bite.
Barbed Tentacles
Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 25 (5d6 + 8) piercing damage, and the target is grappled (escape DC 18).
Until this grapple ends, the target is restrained. The tentacles can grapple only one creature at a time.
Bite
Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 30 (5d8 + 8) piercing damage. If the target is a Large or smaller creature, it must succeed on a DC 18 Dexterity saving throw or be swallowed by the worm. A swallowed creature is blinded and restrained, has total cover against attacks and other effects outside the worm, and takes 21 (6d6) fire damage at the start of each of the worm's turns.
If the worm takes 30 damage or more on a single turn from a creature inside it, the worm must succeed on a DC 21 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the worm. If the worm dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 feet of movement, exiting prone.

description
This invertebrate horror has quivering, barbed tentacles set around its massive, toothy maw. The worm's cracked and stony hide pulses with a dull orange glow, as if it might be composed of primordial lava perpetually on the verge of hardening into solid rock.
Offspring of Calamity: The aberrant creatures known as core spawn are a subterranean breed of heralds, servants, foot soldiers, and lieutenants of the Elder Evils, awakened in the depths by the cataclysmic actions of the Betrayer Gods and their minions. They often appear on the surface world in the wake of seismic events, such as that which created the bottomless Miskath Pit of Eastern Wynandir. Warlocks and cultists sometimes gather together to hasten the arrival of core spawn to the Material Plane, focusing their arcane power on areas of natural seismic instability when the signs and stars are right.
